| Abstract: | Intramolecular coordination in dimethylaluminium phenoxides (with an ortho-substituted ring) was investigated. Only strongly donating groups in the phenoxy ring (COOMe) displayed strong intramolecular coordination. All compounds investigated formed donor-acceptor complexes with hexamethylphosphoramide (HMPA). Dimethylaluminium methylsalicilate coordinated HMPA without splitting the intramolecular carbonyl oxygen—aluminium bond, which suggests formation of the pentacoordinated aluminium atom. |
